North Wales Police says the arrested man has now been released without charge and there will be not further police action. The Health and Safety Executive has taken over the investigation.

We are all deeply shocked by this tragic incident. We made the decision to close the whole mill overnight as a mark of respect for the deceased and his family.
Staff affected by the incident will be offered support going forward, including counselling as required. We will continue to work closely with all parties to identify the cause of the incident.

"We are conducting a thorough investigation and are working to establish the full circumstances surrounding Daniel's tragic death" said Detective Chief Inspector Iain Miller, from British Transport Police.

We’re eager to talk to any of Daniel's friends or acquaintances, particularly anyone who saw him on Saturday night or since then, as they may be able to help our investigation.

We know the last time anyone saw Daniel he was seen sitting on the wall outside the Lady Hamilton public house in Neston, Cheshire in the early hours of Sunday morning.
